Broken-Fall Pressure-Crest Caiman
The low, broad snout and naturally aligned dorsal osteoderms belong to a powerful ambush predator. Paired pressure-sensitive bony crests sit behind the eyes; lateral flow vanes edge the flattened tail. It feeds on medium to large fish and small mammals near the water. Its nest-bay patrol is independent of Fang and K.
Observation TypeField observation
First SeenDay 05 · Day 05 · Outer Catch-Pool Exclusion Line
HabitatThe outer-rim catch pool and a distant nest bay below broken waterfall terraces. The permanent exclusion line keeps observers outside its patrol route; this observation does not describe the sinkhole’s lightless core.
VariantsJuveniles about one meter long; a solitary adult around seven meters. The adult patrols a broad territory rather than gathering with others at the observation line.
Habitat and Mechanism
The outer-rim catch pool and a distant nest bay below broken waterfall terraces. The permanent exclusion line keeps observers outside its patrol route; this observation does not describe the sinkhole’s lightless core.. Waterfall backflow carries pressure waves across the catch pool. Two bony crests behind the eyes register pressure changes, and flattened vanes along the tail help the caiman steer through the return flow. Continuous artificial buoy pulses repeatedly alter its route. Once K stops the continuous pulse and retains intermittent low-frequency ranging, the backflow settles and the solitary adult patrols its distant nest bay on its own.

The low, broad snout and naturally aligned dorsal osteoderms belong to a powerful ambush predator. Paired pressure-sensitive bony crests sit behind the eyes; lateral flow vanes edge the flattened tail. It feeds on medium to large fish and small mammals near the water. Its nest-bay patrol is independent of Fang and K.
Fish scales, tufts of mammal hair, and low slide marks at the pool reveal a food route. Crest and tail anatomy help the adult read pressure and backflow; its patrol marks a dangerous, occupied habitat that must remain undisturbed.
Form and Identification
Juveniles about one meter long; a solitary adult around seven meters. The adult patrols a broad territory rather than gathering with others at the observation line.
- Low broad snout and naturally ordered dorsal osteoderms
- Two bony pressure-sensitive crests behind the eyes
- Flattened tail with lateral flow-guiding vanes
- A solitary, distant patrol in the outer catch pool and nest bay
Observation Rule
No pursuit, baiting, contact, injury, or crossing the catch-pool line. Fang and K change their artificial buoy and withdraw. A distant animal’s route is not an invitation to follow it.
Beyond the Outer Catch-Pool Exclusion Line, Fang and K found fish scales, hair, and a low slide mark. Only a distant pressure-crest silhouette broke the far waterline. They recorded the signs from a safe observation line and did not approach.
